You should get a new piece of tubing. It is now most likely too short (actually most shop install them too short to begin with). Also it is old and could easily fail.
It should be long enough so that it barely stretches at full draw -- just enough tension to keep your peep straight. It should not stretch where it were to part it could snap back and hit you in the eye. By keeping it long enought to just turn the peep you do not have to worry about a failure or an injury to your eye.
Excellent advise.
Most problems folks have with tube style peeps is they (the tubes) are installed incorrectly. Like mentioned above it should be just short enough to align the peep. You shouldalso install your peep as you would if you were using a tubeless peep. Set it so that it aligns when you draw, the tubingshould only be there to make sure it's
perfectly aligned when you draw.
Lots of people just stick the peep in and make the tube do all of the work pulling it into position, that's not how you are supposed to install them. No wonder why they break on people. Tubing too short, tubingtoo old and improperly positioned peep is a recipe for failure.
Even the best made strings/cables can creep especially in extreme weather changes/conditions. All it takes is a 1/4 turn and you can't see through it. With the tube attached this will never happen.
Change your tube at least twice a year. I change mine once before hunting season and once after.It's only afew dollars...won't break the bank.
